2-8-2

Under the Whyte notation for the classification of steam locomotives, 2-8-2 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and two trailing wheels on one axle, also usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike, but at times it was also referred to on some railroads in the United States of America as the McAdoo Mikado and, during World War II, the MacArthur.
